摘要
根据1987～1988年的试验资料,提出了适用于半干旱地区土壤蒸发、农田蒸散、土壤蒸发力与农田蒸散力的测定和计算方法。对农田耗水量的估算和旱地农业的水量平衡研究提供依据。
According to the data of experiment from 1987 to 1988,this paper puts forward the methods of determination and calculation of soil evaporation, evapotranspiration,soil potential evaporation and potential evapotranspiration in the application to the semi-arid regin,both it concerned calculation of the water consumption in farmand and it provided basis for the agricultural recea- rch water balance in dry land.
